An electronics problem disabled the hydraulics system on board Emirates Team New Zealand’s AC72 today, bringing the boat to a halt at the third mark of the second race in the Louis Vuitton Cup final.

Without hydraulics the crew can operate neither the wing or the daggerboards. Leading Luna Rossa by a relatively comfortable 400 metres at the time, Dean Barker and crew could only watch as Luna Rossa closed the gap, rounded the mark and sailed away.
